Özet
Natural radionuclides from the uranium (238U) and thorium (232Th) families, as well as the radioactive isotope potassium, are present in varying concentrations in building materials and other construction products obtained from rock and soil. In Italy, in historical monuments, natural building materials have been largely employed for decorative and structural purposes. In this study the natural radioactivity content in six different materials (grey tuff, basalt lava stone, lava stone, sandstone, magmatic rock and travertine) was measured. The activity concentrations were determined by high purity germanium (HPGe) detector-based gamma spectrometry. The radium equivalent activity (Raeq), indoor absorbed gamma dose rate (Din), the annual effective dose (De), and the internal and external hazard indexes were evaluated to assess the radiation hazard according to the international recommendations.
